SEAL-LOCK FOR CARS.

SPECIFICATION forming part of Letters Patent No. 245,645, dated August16, 1881.

Application filed May 14, 1881.

To all whom it may concern:

Be it known that I, ADELARD FRANK MAR- TEL, of the city of Montreal, inthe county of Hochelaga, in the Province of Quebec,Canada,railway-conductor, have invented certain new and usefulImprovements in Car Seal- Locks and I do hereby declare that thefollowing is a full, clear, and exact description of the invention.

My invention is an improved car seal-lock, consisting of an automaticlock and seal so arranged that the door of the car is sealed and lockedby simply closing the door. It is provided with a shield on one or bothsides of the [5 spring-latch, so that when it is locked an instrumentcannot be inserted to raise the latch, thus preventing the opening ofthe door without breaking the seal.

Figure 1 is a side elevation of the car withmyirnprovedseal-lock,catch,and shield. Fig. 2 is a front view of thecatch. Fig. 3 is a front view of the lock. Fig. 4 is a sectional view ofthe lock-case, showing the spring-latch; and Fig. 5, a seal detached.

A is the car-door, moving in slides, as usual; but when closed its frontincases itself into thejamb of 'the door-frame, so as to allow noopening between the door and door-jarnb.

B is the door-jarnb, provided with a recess 0 in its wholelength toreceive the car-door when closed, and to which the catch G is fitted toreceive the spring-latch D.

C is the lock-casing, provided with a projecting shield, G, to preventthe introduction 5 of any thin instrument or contrivance to raise thespring-latch D when the door is locked and sealed, and to which thespringlatch D is pivoted at about its center by a hollow shaft, in whichis a square or other aperture to re- 0 eeive a key, F, to open it,having its shaft fitted to enter the aperture in the hollow shaft of thespring-latch D, so as to raise it out of the catch G to open the door.

E is the seal-case, in which a flat water-proof seal of any descriptionis inserted, covering (Model) the aperture in the hollow shaft, andleaving a portion of itself exposed, on which any required inscriptionmay be placed, so that the car cannot be opened without perforating theseal with the key by inserting it in the aperture of the hollow shaft ofthe spring-latch D, so as to raise it out of the catch G and open thedoor, thus showingfrom inspection whether the seal has been tamperedwith.

F is the key, having a square or other shaped shaft fitted to enter theaperture in the hollow shaft of the spring-latch D.

G is a catch fitted to the door-jamb B of ear, to receive thespring-latch D to lock the door.

The sealin g of locked cars in an expeditious manner so as to preventaccess thereto without leaving some trace of irregularity behind is oneof the necessities of the present time. Not only to prevent illegalaccess thereto, but also to look and seal the car without undue loss oftime, is much to be desired when combined with simplicity ofconstruction and non-liability to get out of repair.

I am aware of seal-locks being used for the purpose of locking cars.Those I do not claim, as I know there are many devices of the kind inuse; but

What I do claim as my invention is as follows:

1. The combination'of a catch or keeper and a lock provided with aprotruding locking bolt or latch, and having its case provided with ashield to cover the protruding portion of said bolt or latch to preventtampering therewith.

2. In combination with a keeper or catch, a lock having a protrudinglocking bolt or latch, and having its case provided with a shield tocover the protruding portion of said bolt or latch, and with aseal-passage open at the edge or side of the case, through which thebolt pro- 5 A trudes.
